The invention provides a four-way pipeline for pouring. Three liquid outlet channels are communicated with a liquid inlet channel through an inner cavity. Three liquid outlet portions are all sleeved with hollow pipe connecting parts. Convex parts are arranged on the liquid outlet portions. Concave parts which are matched with the convex parts are arranged on the pipe connecting parts. Hollow connectors which are connected with subsequent pipelines are further arranged on the pipe connecting parts. The horizontal height of the ends, connected with the pipe connecting parts, of the liquid outlet channels is smaller than that of the ends, connected with the inner cavity, of the liquid outlet channels. The pipe connecting parts are arranged on the liquid outlet portions, in this way, in specific use, the four-way pipeline is in transition with the subsequent pipelines through the pipe connecting parts, the four-way pipeline can be made to be connected with a new pipeline simply by replacing the corresponding pipe connecting part during pipeline replacement, and using is quite convenient; in addition, the pipeline connectors are arranged on the liquid inlet portions, and thus the universality of the four-way pipeline can be further improved.
